Surface Edit Overview
This widget displays a top down view of the Dynamic Surface currently being edited. This widget is active whenever you are using the 3D Editor or Slice Editor. You can see and modify the current selection in this view as well as the 4D View. The Surface Edit Overview can additionally display an ENC for the area of interest, a Visited/Edited layer and a Partition Grid for Guided Editing operations. The Partition Grid can only be used when you are in Fixed Slice, Free Slice, and Rectangular selection mode. See the section on the 4D Scene Toolbar for more information on selection modes. You can opt out of using the Surface Edit Overview on the General Tab of the Preferences Dialog. Of note in the version 2.2 release of Qimera, the Surface Edit Overview has been redesigned to be more responsive and have a significantly lower memory footprint.

Using Grid Partitions
Grid partitions can be used to navigation the selection and systematically review and edit the entire surface. To move to a new partition tile, simply click in the desired tile and the selection will move. You can also use the movement shortcut keys (W, S, A, D) with the addition of the SHIFT key to move the selection to another tile. Grid partitions can be used with the Fixed, Free, and Rectangular selection modes.
Remember that you can use grid partitions with either the Slice or 3D Editor. To stop using Grid Partitions, simply choose Select Mode on the toolbar or the associated Select Mode menu option.
